Organization, Consolidation and Presentation of Financial Statements [Abstract]
Overview	Note 1 – Overview Gentherm Incorporated, a Michigan corporation, and its consolidated subsidiaries (“Gentherm”, “we”, “us”, “our” or the “Company”) is the global market leader of innovative thermal management and pneumatic comfort technologies for the automotive and medical industries. Automotive products include variable temperature Climate Control Seats, heated automotive interior systems (including heated seats, steering wheels, armrests and other components), battery performance solutions, cable systems, lumbar and massage comfort solutions, valve systems, and other electronic devices. Our automotive products can be found on vehicles manufactured by nearly all the major original equipment manufacturers (“OEMs”) operating in North America and Europe, and several major OEMs in Asia. We operate in locations aligned with our major customers’ product strategies to provide locally enhanced design, integration and production capabilities. Medical products include patient temperature management systems. Our medical products can be found in hospitals throughout the world, primarily in the US, China, Germany and Brazil. The Company is also developing a number of new technologies and products that will help enable improvements to existing products, improve health, wellness and patient outcomes and will lead to new product applications for existing and new and adjacent markets. Basis of Presentation and Significant Accounting Policies The unaudited consolidated condensed financial statements included herein have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to those rules and regulations. The information furnished in the consolidated condensed financial statements include all adjustments (consisting of only normal, recurring adjustments) considered necessary to present fairly the results of operations, financial position and cash flows of the Company. These financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. The operating results for interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. In preparing these financial statements, management was required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. These estimates and assumptions are based on our historical experience, the terms of existing contracts, our evaluation of trends in the industry, information provided by our customers and suppliers and information available from other outside sources, as appropriate. These estimates and assumptions are subject to an inherent degree of uncertainty. We are not presently aware of any events or circumstances that would require us to update such estimates and assumptions or revise the carrying value of our assets or liabilities. Our estimates may change, however, as new events occur and additional information is obtained. As a result, actual results may differ significantly from our estimates, and any such differences may be material to our financial statements. Principles of Consolidation The consolidated condensed financial statements include the accounts of the Company, its wholly owned subsidiaries and those entities in which it has a controlling financial interest. The Company evaluates its relationship with other entities for consolidation and to identify whether such entities are variable interest entities (“VIE”) and to assess whether the Company is the primary beneficiary of such entities. Investments in entities in which Gentherm does not have control but does have the ability to exercise significant influence over operating and financial policies are accounted for under the equity method. When Gentherm does not have the ability to exercise significant influence (generally when ownership interest is less than 20 %), investments in entities are measured at cost, less impairments, adjusted for observable price changes in orderly transactions for identical or similar investments of the same issuer. Variable Interest Entities The Company maintains an ownership interest in a VIE, Carrar Ltd. (“Carrar”). Carrar is a technology developer of advanced thermal management systems for the electric mobility market. The Company determined that Carrar is a VIE; however, the Company does not have a controlling financial interest or have the power to direct the activities that most significantly affect the economic performance of the investment. Therefore, the Company has concluded that it is not the primary beneficiary. Gentherm’s investment in Carrar is measured at cost, less impairments, adjusted for observable price changes in orderly transactions for identical or similar investments of the same issuer. The Carrar investment was $ 5,700 and $ 5,200 as of June 30, 2023 and December 31, 2022 , respectively, and is recorded in Other non-current assets in the consolidated condensed balance sheets. Revenue Recognition The Company has no material contract assets or contract liabilities as of June 30, 2023. The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if the benefits of those costs are expected to be realized for a period greater than one year . Total capitalized costs to obtain a contract were $ 3,849 and $ 2,239 as of June 30, 2023 and December 31, 2022 , respectively. These amounts are recorded in Other non-current assets in the consolidated condensed balance sheets and are being amortized into Product revenues in the consolidated condensed statements of (loss) income over the expected production life of the applicable program.

Restructuring and Related Activities [Abstract]
Restructuring and Impairments	Note 3 – Restructuring and Impairments The Company continuously monitors market developments, industry trends and changing customer needs and in response, may undertake restructuring actions, as necessary, to execute management’s strategy, streamline operations and optimize the Company’s cost structure. Restructuring actions may include the realignment of existing manufacturing footprint, facility closures, or similar actions, either in the normal course of business or pursuant to significant restructuring programs. These actions may result in employees receiving voluntary or involuntary employee termination benefits, which are mainly statutory requirements or other contractual agreements. Voluntary termination benefits are accrued when an employee accepts the related offer. Involuntary termination benefits are accrued upon the commitment to a termination plan and when the benefit arrangement is communicated to affected employees, or when liabilities are determined to be probable and estimable, depending on the existence of a substantive plan for severance or termination. Manufacturing Footprint Rationalization During 2019, the Company committed to a restructuring plan (“Plan”) to improve the Company’s manufacturing productivity and rationalize its footprint. Under this Plan, the Company relocated and consolidated certain automotive electronics manufacturing plants in North America and China.

During the second quarter of 2023, the Company’s Medical reporting unit did not perform in-line with forecasted results primarily driven by slower than anticipated revenue growth. As a result, an indicator of impairment was identified and the Company performed an interim quantitative assessment as of June 30, 2023. The results of this quantitative analysis indicated the carrying value of the reporting unit exceeded the fair value of the reporting unit by $ 17,086 , and accordingly an impairment expense was recorded for $ 19,509 that includes the associated deferred tax effect that was measured using the simultaneous equation method. The Company utilized an income approach to estimate the fair value of the reporting unit and a market valuation approach to further support this analysis (level 3). The income approach was based on projected debt-free cash flow that was discounted to the present value using discount factors that considered the timing and risk of cash flows. Fair value was estimated using internally developed forecasts, as well as commercial and discount rate assumptions. The discount rate used was the value-weighted average of our estimated cost of equity and of debt (“cost of capital”) derived using both known and estimated customary market metrics. Our weighted average cost of capital includes a company specific risk premium to address the risks associated with achieving the projected revenue and profitability growth rates. Other significant assumptions included terminal value growth rates and terminal value margin rates. Our ability to realize the future cash flows used in our calculations is affected by factors such as the success of strategic initiatives, changes in economic conditions, changes in our operating performance and changes in our business strategies. To further support the fair value estimate determined by the income approach, the Company utilized a market valuation approach to estimate the fair value of the Medical reporting unit. The market approach considered historical and anticipated financial metrics of the Medical reporting unit and applied valuation multiples based on recent observed transactions involving companies similar enough to the Medical reporting unit from which to draw meaningful conclusions.

The Second Amended and Restated Credit Agreement provides for a $ 500,000 secured revolving credit facility (the “Revolving Credit Facility”), with a $ 50,000 sublimit for swing line loans and a $ 15,000 sublimit for the issuance of standby letters of credit. Any amount of the facility utilized for swing line loans or lett ers of credit outstanding will reduce the amount available under the Second Amended and Restated Credit Agreement. The Company had no outsta nding letters of credit issued as of June 30, 2023 and December 31, 2022. Subject to specified conditions, Gentherm can increase the Revolving Credit Facility or incur secured term loans in an aggregate amount of up to $ 200,000 . The Second Amended and Restated Credit Agreement matures on June 10, 2027 . The U.S. borrowers and guarantors participating in the Second Amended and Restated Credit Agreement also entered into a Second Amended and Restated Pledge and Security Agreement (the “Second Amended and Restated Security Agreement”). The Second Amended and Restated Security Agreement grants a security interest to the Agent in substantially all of the personal property of the Company and its U.S. subsidiaries designated as borrowers to secure their respective obligations under the Second Amended and Restated Security Agreement, including the stock and membership interests of specified subsidiaries (limited to 66 % of the stock in the case of certain non-U.S. subsidiaries). In addition to the security obligations, all obligations under the Second Amended and Restated Credit Agreement (including all obligations of any U.S. or non-U.S. loan party) are unconditionally guaranteed by certain of Gentherm’s domestic subsidiaries, and the German subsidiary borrowers and certain other foreign subsidiaries guarantee all obligations of the non-U.S. loan parties under the Second Amended and Restated Credit Agreement. The Second Amended and Restated Credit Agreement restricts, among other things, the amount of dividend payments the Company can make to shareholders. The Second Amended and Restated Credit Agreement contains covenants, that, among other things, (i) prohibit or limit the ability of the borrowers and any material subsidiary to incur additional indebtedness, create liens, pay dividends, make certain types of investments (including acquisitions), enter into certain types of transactions with affiliates, prepay other indebtedness, sell assets or enter into certain other transactions outside the ordinary course of business, and (ii) require that Gentherm maintain a minimum Consolidated Interest Coverage Ratio and a maximum Consolidated Net Leverage Ratio (based on consolidated EBITDA for the applicable trailing four fiscal quarters) as of the end of any fiscal quarter. The Second Amended and Restated Credit Agreement also contains customary events of default. As of June 30, 2023, the Company was in compliance with the terms of the Second Amended and Restated Credit Agreement. The Second Amended and Restated Credit Agreement additionally contains customary events of default. Upon the occurrence of an event of default, the amounts outstanding under the Revolving Credit Facility may be accelerated and may become immediately due and payable. Under the Second Amended and Restated Credit Agreement, U.S. Dollar denominated loans bear interest at either a base rate (“Base Rate Loans”) or Term SOFR rate (“Term SOFR Rate Loans”), plus a margin (“Applicable Rate”). The rate for Base Rate Loans is equal to the highest of the Federal Funds Rate plus 0.50 %, Bank of America’s prime rate, or the Term SOFR rate plus 1.00 %. The rate for Term SOFR Rate Loans denominated in U.S. Dollars is equal to the forward-looking Secured Overnight Financing Rate (“SOFR”) term rate administered by the CME with a term of one month. All loans denominated in a currency other than the U.S. Dollar must be Term SOFR Rate Loans. Interest is payable at least quarterly. Additionally, a commitment fee of between 0.175 % to 0.300 %, which will vary based on the Consolidated Net Leverage Ratio, as defined in the Second Amended and Restated Credit Agreement, is payable on the average daily unused amounts under the Revolving Credit Facility. The Applicable Rate varies based on the Consolidated Net Leverage Ratio reported by the Company. As long as the Company is not in default of the terms and conditions of the Second Amended and Restated Credit Agreement, the lowest and highest possible Applicable Rate is 1.125 % and 2.125 %, respectively, for Term SOFR Rate Loans and 0.125 % and 1.125 %, respectively, for Base Rate Loans. Borrowing availability is subject to, among other things, the Company’s compliance with the minimum Consolidated Interest Coverage Ratio and the maximum Consolidated Net Leverage Ratio as of the end of any fiscal quarter. Based upon consolidated EBITDA for the trailing four fiscal quarters calculated for purposes of the Consolidated Net Leverag e Ratio, $ 282,732 r emained available as of June 30, 2023 for additional borrowings under the Second Amended and Restated Credit Agreement subject to specified conditions that Gentherm currently satisfies. In connection with the Second Amended and Restated Credit Agreement, the Company incurred debt issuance costs of $ 1,417 , which have been capitalized and will be amortized into Interest expense, net over the term of the credit facility. The scheduled principal maturities of our debt as of June 30, 2023 were as follows: U.S. Other Debt Total 2023 $ — $ 471 $ 471 2024 — 434 434 2025 — 151 151 2026 — 69 69 2027 217,000 — 217,000 2028 — — — Total $ 217,000 $ 1,125 $ 218,125

Commitments and Contingencies	Note 7 – Commitments and Contingencies Legal and other contingencies The Company may be subject to various legal actions and claims in the ordinary course of its business, including those arising out of breach of contracts, intellectual property rights, environmental matters, regulatory matters and employment-related matters. The Company establishes accruals for matters which it believes that losses are probable and can be reasonably estimated. Although it is not possible to predict with certainty the outcome of these matters, the Company is of the opinion that the ultimate resolution of these matters will not have a material adverse effect on its results of operations or financial position. Product liability and warranty reserves are recorded separately from legal reserves. Product Liability and Warranty Matters In the event that the Company’s products fail to perform as expected or result in alleged bodily injury or property damage, our products may subject us to warranty claims and product liability. If any of our products are or are alleged to be defective, we may be required to participate in a recall or other corrective action involving such products. The Company maintains liability insurance coverage at levels based on commercial norms and historical claims experience. The Company can provide no assurances that it will not experience material claims or liabilities in the future or that it will not incur significant costs to defend such claims. The Company accrues warranty obligations for products sold based on management estimates of future failure rates and current claim cost experience, with support from the sales, engineering, quality and legal functions. Using historical information available to the Company, including any claims filed by customers, the warranty accrual is adjusted quarterly to reflect management’s estimate of future claims. The following is a reconciliation of the changes in accrued warranty costs: Six Months Ended June 30, 2023 2022 Balance at the beginning of the period $ 2,380 $ 1,916 Warranty claims paid ( 1,673 ) ( 623 ) Warranty expense for products shipped during the current period 2,215 818 Adjustments to warranty estimates from prior periods ( 32 ) ( 171 ) Adjustments due to currency translation 10 ( 41 ) Balance at the end of the period $ 2,900 $ 1,899 Other matters Purchase commitments for materials, supplies, services and capital expenditures, as part of the normal course of business, are generally consistent from year to year. In addition, due to supply shortages of semiconductors, the Company has entered into agreements with various suppliers to reserve the right to purchase certain semiconductor chips over rolling periods of 12 - 24 months , with volume commitments determined based on our anticipated production requirements. As of June 30, 2023 , the Company’s total commitments for these semiconductor chip agreements was $ 34,646 . Such agreements provide the Company with priority access to semiconductor chips as they become available, however, these agreements do not guarantee that our suppliers will meet the timing and quantities requested by Gentherm. All other purchase commitments as of June 30, 2023 were immaterial.

Earnings Per Share [Abstract]
(Loss) Earnings Per Share	Note 8 – (Loss) Earnings Per Share Basic (loss) earnings per share are computed by dividing net (loss) income by the weighted average number of shares of Common Stock outstanding during the period. The Company’s diluted (loss) earnings per share give effect to all potential shares of Common Stock outstanding during a period that do not have an anti-dilutive impact to the calculation. In computing the diluted (loss) earnings per share, the treasury stock method is used in determining the number of shares assumed to be issued from the exercise of Common Stock equivalents. The following table illustrates earnings per share and the weighted average shares outstanding used in calculating basic and diluted earnings per share: Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 Net (loss) income $ ( 1,551 ) $ 7,072 $ 6,412 $ 18,819 Basic weighted average shares of Common Stock outstanding 33,018,939 33,119,085 33,099,817 33,077,029 Dilutive effect of stock options, restricted stock awards and restricted stock units — 307,038 228,160 344,958 Diluted weighted average shares of Common Stock outstanding 33,018,939 33,426,123 33,327,977 33,421,987 Basic (loss) earnings per share $ ( 0.05 ) $ 0.21 $ 0.19 $ 0.57 Diluted (loss) earnings per share $ ( 0.05 ) $ 0.21 $ 0.19 $ 0.56 The following table represents Common Stock issuable upon the exercise of certain restricted stock awards and restricted stock units that have been excluded from the diluted earnings calculation because the effect of their inclusion would be anti-dilutive.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments	Note 9 – Financial Instruments Derivative Financial Instruments The Company is exposed to various market risks including, but not limited to, changes in foreign currency exchange rates, changes in interest rates and price fluctuations of certain material commodities such as copper. Market risks for changes in interest rates relate primarily to its debt obligations under the Second Amended and Restated Credit Agreement. Foreign currency exchange risks are attributable to sales to foreign customers and purchases from foreign suppliers not denominated in a location’s functional currency, foreign plant operations, intercompany indebtedness, intercompany investments and include exposures to the Euro, Mexican Peso, Canadian Dollar, Hungarian Forint, North Macedonian Denar, Ukrainian Hryvnia, Japanese Yen, Chinese Renminbi, Korean Won, Czech Koruna and Vietnamese Dong. The Company regularly enters into derivative contracts with the objective of managing its financial and operational exposure arising from these risks by offsetting gains and losses on the underlying exposures with gains and losses on the financial instruments used to hedge them. The decision of whether and when to execute derivative financial instruments, along with the duration of the instrument, may vary from period to period depending on market conditions, the relative costs of the instruments and capacity to hedge. The duration is linked to the timing of the underlying exposure, with the connection between the two being regularly monitored. The Company does not enter into derivative financial instruments for speculative or trading purposes. Some derivative contracts do not qualify for hedge accounting; for other derivative contracts, we elect to not apply hedge accounting. The Company’s designated hedging relationships are formally documented at the inception of the hedge, and hedges must be highly effective in offsetting changes to future cash flows on hedged transactions both at the inception of a hedge and on an ongoing basis to be designated for hedge accounting treatment. For derivative contracts which can be classified as a cash flow hedge, the effective portion of the change in the fair value of the derivative is recorded to Accumulated other comprehensive loss in the consolidated condensed balance sheets. When the underlying hedge transaction is realized, the gain or loss included in Accumulated other comprehensive loss is recorded in earnings in the consolidated condensed statements of (loss) income on the same line as the gain or loss on the hedged item attributable to the hedged risk. The Company records the ineffective portion of designated foreign currency and copper commodity hedging instruments, if any, to Cost of sales in the consolidated condensed statements of (loss) income. Cash flows associated with derivatives are reported in Net cash provided by (used in) operating activities in the consolidated condensed statements of cash flows. The Company uses an income approach to value derivative instruments, analyzing quoted market prices to calculate the forward values and then discounting such forward values to the present value using benchmark rates at commonly quoted intervals for the instrument’s full term. The Company is party to a floating-to-fixed interest rate swap agreement with a notional amount of $ 100,000 and a maturity date of July 2025 . This interest rate swap is an undesignated hedge of the Company’s exposure to interest payment fluctuations on a portion of the Revolving Credit Facility borrowings that were drawn for the acquisitions of Alfmeier and Dacheng. The periodic changes in fair value is recognized in Interest expense, net. Information related to the recurring fair value measurement of derivative instruments in our consolidated condensed balance sheet as of June 30, 2023 is as follows: Asset Derivatives Liability Derivatives Fair Value Notional Amount Balance Sheet Fair Balance Sheet Fair Net Asset/ Derivatives Designated as Cash Flow Hedges Foreign currency derivatives Level 2 $ 54,861 Other current assets $ 9,380 Other current liabilities $ — $ 9,380 Derivatives Not Designated as Hedging Instruments Interest rate contracts Level 2 $ 100,000 Other current assets $ 3,445 Other current liabilities $ — $ 3,445 Information related to the recurring fair value measurement of derivative instruments in our consolidated condensed balance sheet as of December 31, 2022 is as follows: Asset Derivatives Liability Derivatives Fair Value Notional Amount Balance Sheet Fair Balance Sheet Fair Net Asset/ Derivatives Designated as Cash Flow Hedges Foreign currency derivatives Level 2 $ 40,063 Other current assets $ 3,791 Other current liabilities $ — $ 3,791 Derivatives Not Designated as Hedging Instruments Interest rate contracts Level 2 $ 100,000 Other current assets $ 2,772 Other current liabilities $ — $ 2,772 Information relating to the effect of derivative instruments on our consolidated condensed statements of (loss) income and the consolidated condensed statements of comprehensive (loss) income is as follows: Three Months Ended June 30, Six Months Ended June 30, Location (Income/(Loss)) 2023 2022 2023 2022 Derivatives Designated as Cash Flow Hedges Foreign currency derivatives Cost of sales – income $ 1,984 $ 333 $ 3,043 $ 486 Other comprehensive income (loss) 2,905 ( 316 ) 5,588 294 Total foreign currency derivatives $ 4,889 $ 17 $ 8,631 $ 780 Commodity derivatives Cost of sales – income $ — $ — $ — $ 19 Other comprehensive loss — — — ( 6 ) Total commodity derivatives $ — $ — $ — $ 13 Derivatives Not Designated as Hedging Instruments Foreign currency derivatives Foreign currency gain $ — $ 482 $ — $ 482 Total foreign currency derivatives $ — $ 482 $ — $ 482 Interest rate contracts Interest expense, net $ 1,371 $ ( 693 ) $ 672 $ ( 693 ) Total interest rate derivatives $ 1,371 $ ( 693 ) $ 672 $ ( 693 ) The Company did no t incur any hedge ineffectiveness during the three and six months ended June 30, 2023 and 2022. Accounts Receivable Factoring The Company sells certain customer trade receivables on a non-recourse basis under factoring arrangements with designated financial institutions. The sale of receivables under these agreements is considered an off-balance sheet arrangement to the Company and is accounted for as a true sale and excluded from accounts receivable in the consolidated condensed balance sheets. These factoring arrangements include a deferred purchase price component in which a portion of the purchase price for the receivable is paid by the financial institution in cash upon sale and the remaining portion is recorded as a deferred purchase price receivable and paid at a later date. Deferred purchase price receivables are recorded in Other current assets within the consolidated condensed balance sheets. Cash proceeds received upon the sale of the receivables are included in Net cash provided by (used in) operating activities and the cash proceeds received on the deferred purchase price receivables are included in Net cash used in investing activities. All factoring arrangements incorporate customary representations, including representations as to validity of amounts due, completeness of performance obligations and absence of commercial disputes. Receivables factored and availability under receivables factoring agreements balances as of June 30, 2023 and December 31, 2022 were as follows: June 30, 2023 December 31, 2022 Receivables factored and outstanding $ 21,623 $ 19,108 Amount available under the credit limit 2,471 5,034 Collective factoring limit $ 24,094 $ 24,142 Trade receivables sold and factoring fees incurred during the three and six months ended June 30, 2023 and 2022 were as follows: Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 Trade receivables sold $ 38,261 $ — $ 76,801 $ — Factoring fees incurred 207 — 368 —

Fair Value Measurements

Fair Value Measurements	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 10 – Fair Value Measurements Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Fair value measurements are based on one or more of the following three valuation techniques: Market : This approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. Income : This approach uses valuation techniques to convert future amounts to a single present value amount based on current market expectations. Cost : This approach is based on the amount that would be required to replace the service capacity of an asset (replacement cost). The Company uses the following fair value hierarchy to measure fair value into three broad levels, which are described below: Level 1 : Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs. Level 2 : Inputs, other than quoted market prices included in Level 1, that are observable either directly or indirectly for the asset or liability. Level 3 : Unobservable inputs that are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs. Items Measured at Fair Value on a Recurring Basis Except for derivative instruments (see Note 9) and pension plan assets, the Company had no material financial assets and liabilities that were carried at fair value at June 30, 2023 and December 31, 2022. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible and also considers counterparty credit risk in its assessment of fair value. Items Measured at Fair Value on a Nonrecurring Basis The Company measures certain assets and liabilities at fair value on a non-recurring basis. As these nonrecurring fair value measurements are generally determined using unobservable inputs, these fair value measurements are classified within Level 3 of the fair value hierarchy. The Company utilized a third-party to assist in the Level 3 fair value estimates of other intangible assets for recent acquisitions (see Note 2) and goodwill of the Medical reporting unit (see Note 5). The estimated fair values of these assets were based on third-party valuations and management’s estimates, generally utilizing income and market approaches. As of June 30, 2023, and December 31, 2022 , there were no other significant assets or liabilities measured at fair value on a non-recurring basis. Items Not Carried at Fair Value The Company uses an income valuation technique to measure the fair values of its debt instruments by converting amounts of future cash flows to a single present value amount using rates based on current market expectations (Level 2 inputs). As of June 30, 2023, and December 31, 2022 , the carrying values of the indebtedness under the Company’s Second Amended and Restated Credit Agreement were not materially different than the estimated fair values because the interest rates on variable rate debt approximated rates currently available to the Company (see Note 6).

Income Taxes

Income Taxes	6 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Note 13 – Income Taxes At the end of each interim period, the Company makes an estimate of the annual expected effective income tax rate and applies that rate to its ordinary year-to-date earnings or loss. The income tax provision or benefit related to unusual or infrequent items, if applicable, that will be separately reported or reported net of their related tax effects are individually computed and recognized in the interim period in which those items occur. In addition, the effect of changes in enacted tax laws or rates, tax status, judgment on the realizability of a beginning-of-the-year deferred tax asset in future years or income tax contingencies is recognized in the interim period in which the change occurs. The computation of the annual expected effective income tax rate at each interim period requires certain estimates and assumptions including, but not limited to, the expected pre-tax income (or loss) for the year, projections of the proportion of income (and/or loss) earned and taxed in respective jurisdictions, permanent and temporary differences, and the likelihood of the realizability of deferred tax assets generated in the current year. Jurisdictions with a projected loss for the year for which no tax benefit can be recognized due to a valuation allowance are excluded from the estimated annual effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter, based upon the composition and timing of actual earnings compared to annual projections. The estimates used to compute the provision or benefit for income taxes may change as new events occur, additional information is obtained or as our tax environment changes. To the extent that the expected annual effective income tax rate changes, the effect of the change on prior interim periods is included in the income tax provision in the period in which the change in estimate occurs. A summary of the provision for income taxes and the corresponding effective tax rate for the three and six months ended June 30, 2023 and 2022, is shown below: Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 Income tax expense $ 4,842 $ 3,919 $ 8,570 $ 8,214 Earnings before income tax $ 3,291 $ 10,991 $ 14,982 $ 27,033 Effective tax rate 147.1 % 35.7 % 57.2 % 30.4 % Income tax expense was $ 4,842 for the three months ended June 30, 2023 on earnings before income tax of $ 3,291 , representing an effective tax rate of 147.1 % . The pre-tax earnings included the effect of an impairment loss of $ 19,509 with a tax benefit of $ 2,423 . The effective tax rate differed from the U.S. Federal statutory rate of 21.0 % primarily due to the impact of the tax benefit related to the impairment loss, income taxes on foreign earnings taxed at rates varying from the U.S. statutory rate, the unfavorable impact of the global intangible low-tax income (“GILTI”) and an impact related to legal entity restructuring, partially offset by the impact of research and development credits in various jurisdictions. Income tax expense was $ 3,919 for the three months ended June 30, 2022 on earnings before income tax of $ 10,991 , representing an effective tax rate of 35.7 % . The effective tax rate differed from the U.S. Federal statutory rate of 21.0 % primarily due to the impact of income taxes on foreign earnings taxed at rates varying from the U.S. statutory rate, the unfavorable impact of the GILTI, and the quarterly accrual for uncertain tax positions partially offset by the impact of certain favorable tax effects on equity vesting. Income tax expense was $ 8,570 for the six months ended June 30, 2023 on earnings before income tax of $ 14,982 , representing an effective tax rate of 57.2 % . The pre-tax earnings included the effect of an impairment loss of $ 19,509 with a tax benefit of $ 2,423 . The effective tax rate differed from the U.S. Federal statutory rate of 21 % primarily due to the impact of the tax benefit related to the impairment loss, income taxes on foreign earnings taxed at rates varying from the U.S. statutory rate, the unfavorable impact of GILTI, the quarterly accrual for uncertain tax positions and an impact related to legal entity restructuring, partially offset by the impact of research and development credits in various jurisdictions and certain favorable tax effects of equity vesting. Income tax expense was $ 8,214 for the six months ended June 30, 2022 on earnings before income tax of $ 27,033 , representing an effective tax rate of 30.4 % . The effective tax rate differed from the U.S. Federal statutory rate of 21.0 % primarily due to the impact of income taxes on foreign earnings taxed at rates varying from the U.S. statutory rate, the unfavorable impact of GILTI, and the quarterly accrual for uncertain tax positions partially offset by the impact of certain favorable tax effects of equity vesting.

Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies The unaudited consolidated condensed financial statements included herein have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to those rules and regulations. The information furnished in the consolidated condensed financial statements include all adjustments (consisting of only normal, recurring adjustments) considered necessary to present fairly the results of operations, financial position and cash flows of the Company. These financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. The operating results for interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. In preparing these financial statements, management was required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. These estimates and assumptions are based on our historical experience, the terms of existing contracts, our evaluation of trends in the industry, information provided by our customers and suppliers and information available from other outside sources, as appropriate. These estimates and assumptions are subject to an inherent degree of uncertainty. We are not presently aware of any events or circumstances that would require us to update such estimates and assumptions or revise the carrying value of our assets or liabilities. Our estimates may change, however, as new events occur and additional information is obtained. As a result, actual results may differ significantly from our estimates, and any such differences may be material to our financial statements.
Principles of Consolidation	Principles of Consolidation The consolidated condensed financial statements include the accounts of the Company, its wholly owned subsidiaries and those entities in which it has a controlling financial interest. The Company evaluates its relationship with other entities for consolidation and to identify whether such entities are variable interest entities (“VIE”) and to assess whether the Company is the primary beneficiary of such entities. Investments in entities in which Gentherm does not have control but does have the ability to exercise significant influence over operating and financial policies are accounted for under the equity method. When Gentherm does not have the ability to exercise significant influence (generally when ownership interest is less than 20 %), investments in entities are measured at cost, less impairments, adjusted for observable price changes in orderly transactions for identical or similar investments of the same issuer.
Variable Interest Entities	Variable Interest Entities The Company maintains an ownership interest in a VIE, Carrar Ltd. (“Carrar”). Carrar is a technology developer of advanced thermal management systems for the electric mobility market. The Company determined that Carrar is a VIE; however, the Company does not have a controlling financial interest or have the power to direct the activities that most significantly affect the economic performance of the investment. Therefore, the Company has concluded that it is not the primary beneficiary. Gentherm’s investment in Carrar is measured at cost, less impairments, adjusted for observable price changes in orderly transactions for identical or similar investments of the same issuer. The Carrar investment was $ 5,700 and $ 5,200 as of June 30, 2023 and December 31, 2022 , respectively, and is recorded in Other non-current assets in the consolidated condensed balance sheets.
Revenue Recognition	Revenue Recognition The Company has no material contract assets or contract liabilities as of June 30, 2023. The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if the benefits of those costs are expected to be realized for a period greater than one year . Total capitalized costs to obtain a contract were $ 3,849 and $ 2,239 as of June 30, 2023 and December 31, 2022 , respectively. These amounts are recorded in Other non-current assets in the consolidated condensed balance sheets and are being amortized into Product revenues in the consolidated condensed statements of (loss) income over the expected production life of the applicable program.
